TwoB or not twoB: differential transmission at glutamatergic mossy fiber-interneuron synapses in the hippocampus

Trends Neurosci. 2002 Dec;25(12):600-3. doi: 10.1016/s0166-2236(02)02259-2.

Abstract

Mossy fiber (MF) synapses are key stations for flow of information through the hippocampal formation. A major component of the output of the MF system is directed towards inhibitory interneurons. Recent studies have revealed that the functional properties of MF-interneuron synapses differ substantially from those of MF-CA3 pyramidal neuron synapses. Mossy-fiber-interneuron synapses in the stratum lucidum represent a continuum of functional subtypes, in which the subunit composition of postsynaptic AMPA receptors and NMDA receptors appears to be regulated in a coordinated manner.
